SUBJECT:

REQUEST FOR ADDITIONAL. INFORMATION FOR THE REVIEW OF THE CALVERT CLIFFS NUCLEAR POWER PLANT, UNIT NOS.1 & 2, INTEGRATED PLANT ASSESSMENT REPORT FOR THE SAFETY INJECTION SYSTEM (TAC NOS. MA1108. MA1109, AND M99222)

Dear Mr. Cruse:

By letter dated March 3,1998, Baltimore Gas and Electric Company (BGE) submitted for review the Safety injecticn System (5.15) integrated plant assessment technical report as attached to the " Request for Review and Approval of System and Commodity Reports for License Renewal." BGE requested that the Nuclear Regulatory Commission (NRC) staff review the Safety injection System (5.15) report to determine if this report meets the requirements of 10 CFR 54.21(a), " Contents of application-technicalinformation," and the demonstration required by 10 CFR 54.29(a)(1), " Standards for issuance of a renewed license," to support an application for license renewalif BGE applied in the future. By letter dated April 8,1998, BGE formally submitted its license renewal application.

The NRC staff has reviewed the Safety injection System (5.15) report against the requirements of 10 CFR 54.21(a)(1),10 CFR 54.21(a)(3). By letter dated April 4,1996, the staff approved BGE's methodology for meeting the requirements of 10 CFR 54.21(a)(2). Based on a review of the information submitted, the staff has identified in the enclosure, areas where additional information related to scoping is needed to complete its review. Should the staff have additional information needs related to aging management they will be forwarded under a separate correspondence.

Please provide a schedule by letter or telephonically for the submittal of your responses within 30 days of the receipt of this letter. Additionally, the staff would be willing to meet with BGE prior to the submittal of the responses to provide clarifications of the staff's requests for additionalinformation.

Sincerely, MMN David L. Solorio, Project Manager License Renewal Project Directors.te Division of Reactor Program Management Office of Nuclear Reactor Regulat.on Docket Nos. 50-317 and 50-318 s

n REQUEST FOR ADDITIONAL INFORMATION CALVERT CLIFFS NUCLEAR POWER PLANT. UNIT NOS.1 & 2 SAFETY INJECTION SYSTEM INTEGRATED PLANT ASSESSMENT. SECTION 5.15 DOCKET NOS. 50-317 AND 50-318

$_ection 5.15.1 - Scopina 1.

10 CFR 54.21 (a)(1) states that valve bodies are passive. Page 5.15-12 identifies 29 device types as having only active functions, solenoid valves being one of these 29 components. The drawing on page 5.15.6 and 5.15.7 show solenoid valve bodies being within the evaluation boundary. Provide a justification for not including the pressure boundary function of solenoid valve bodies as being within the scope of the aging management review.

2.

Page 6.3 3 (Rev.18) of the Calvert Cliffs Nuclear Power Plant (CCNPP) Updated Final Safety Analysis Report (UFSAR) indicates that there is a small drain valve controlled remotely from the Control Room, which is intended to drain any leakage from the reactor coolant system into the safety injection system. Was this drain valve subjected to an l

aging management review (AMR)? If so, provide a cross reference to where this is addressed in the license renewal application (LRA). If not, provide the basis for exclusion.

3.

Page 6.3-14 (Rev. 21) of the CCNPP UFSAR indicates that the containment sump suctions are enclnsed by particulate screens. Are these screens included within the l

AMR? If so, provide a cross reference to where they are addressed in the LRA. If not, i

provide the basis for exclusion.
